"Meets X per manufacturer" is our shorthand for any of the manufacturer's own phrases: meets, meets or exceeds, approved, or recommended for applications requiring. It is the manufacturer's claim, not an approval by Coolant.com or by the vehicle maker. Codes are copied as published. Some sources list codes for compatibility rather than formal approval. The wording above shows which.

Compatibility notes
- If your owner's manual calls for MS-12106, PEAK lists that code for this product. Read the exact wording above, and confirm against your manual.
- Chemistry is listed as OAT. Mixing different chemistries can shorten coolant life. See OAT vs HOAT vs IAT and use the mixing checker before topping up.
- Colour is listed as Purple. Colour is a dye, not a spec, so two coolants of the same colour can be different chemistries. See coolant colours explained.
- Sold premixed: pour as supplied. Do not add water unless the label says to.
